Patent Images
1. A biometric authentication system comprising:
- an image capture device configured to generate first biometric data of a user and second biometric data of the user, based on reflected infrared light reflected from an object;
a processor configured to receive and process the first and second biometric data to generate first feature data associated with the first biometric data, and second feature data associated with the second biometric data; and
an authentication unit configured to perform authentication of the user based on at least one of the first feature data and the second feature data.

Abstract
A biometric authentication system and apparatus are provided. The system includes an image capture device, a processor and an authentication unit. The image capture device generates first and second biometric data of a user based on reflected infrared light reflected from an object. The processor processes the first and second biometric data to generate first and second feature data. The first feature data is associated with the first biometric data, and the second feature data is associated with the second biometric data. The authentication unit performs authentication of the user based on at least one of the first feature data and the second feature data.

13. A biometric authentication system comprising:
-
a first image capture device configured to generate first biometric data of a user and second biometric data of the user, based on reflected infrared light reflected from an object; a second image capture device configured to generate color data based on reflected visible light reflected from the object; a first processor configured to process the first and second biometric data to generate first associated with the first biometric data, and second feature data associated with the second biometric data; a second processor configured to process the color data to generate a third feature data associated with the color data; and an authentication unit configured to perform authentication of the user based on at least one of the first feature data, the second feature data and the third feature data. - View Dependent Claims (14, 15, 16)

18. A biometric authentication apparatus comprising:
-
an image capture device configured to receive a reflected infrared (IR) signal from a portion of a person, and to provide depth data of the portion of the person and IR data of the portion of the person; a first processor configured to convert the depth data to three-dimensional data (3D) data, align the 3D data based on reference data, separate the aligned 3D data into object data and background data, and to extract first feature data associated with a shape of the portion of the person from the object data; a second processor configured to separate a region of interest (ROI) of the portion of the person from IR data using the object data from the first processing unit, and to extract direction components from the ROI, frequency components from the ROI, or both the direction components and the frequency components, as second feature data; and an authentication unit configured to perform authentication of the person based on at least one of the first feature data and the second feature data. - View Dependent Claims (19, 20)
